Working Principle of QM48T14120-NBB0G

The operation of the QM48T14120-NBB0G DC-DC Converter is based on the principles of Voltage Multiplication and Pulse Width Modulation (PWM). This involves the application of a high frequency voltage, which is then modulated by the control circuit to create a stable and efficient DC voltage output.The voltage multiplication works by using a high-voltage switching transistor to charge a storage capacitor. This capacitor is maintained at a certain level, and a feedback circuit is used to control the discharge of the capacitor, thus controlling the output voltage of the converter.The PWM determines the duration of the high-frequency voltage pulses, which are modulated to create the stable DC output. The duration of the pulses is controlled by the control circuit, and the duty cycle can be changed to adjust the output voltage.
